This is false. MTP is different from USB mass storage (which is what a flash drive uses).Plugging the phone in as an MTP device should mean it works the same as a flash drive ... except clearly it doesnt!.
The only OS that works flawlessly with MTP is Windows.
I have connection issues too when using MTP (particularly annoying when phone goes to sleep during transfers) and also prefer the older mass storage.Hmm.... define flawlessly. lol.
I *always* have issues with MTP in windows, especially when trying to move multiple files around. It's annoying.
